CDROM & Joystick:
Both work, but the interface needs to be rethought. Currently,
they are similar to the pysdl interface (which is too similar
to the C interface)
Surfarray:
Doesn't support all surface types between all array types. Best
support is for 32bit surfaces.
There are likely plenty of others. This is an early release, and much
testing is pending.
